Magnetic levitation is attractive alternative for fast commuting. The practice of it is not so much as one would expect. Administrative and governing bodies look at funding limitations and risks which are justifiable also. Education, systematic steps in understanding and attempts at modeling, DIY, Toy models etcetera, are also not as many as needed for this technology to take off. This work attempts at explaining the gravity aspects, the electromagnetic aspects, especially separating the single magnet repulsive force, understanding aspects for the practitioners to derive help from a self study. Some useful references are cited. Key word: Maglev, forces from gravitational aspects and electromagnetic aspects, Para, Dia and Ferromagnetic roles, fundamental laws to be understood, design criteria, historical and cost related.

The purpose of this report is to examine the newly developing field of magnetic levitation and its applications in transportation. The magnetic levitation train will be analyzed as well as what makes it the new evolving mode of transportation. The "maglev" train's predecessors will be briefly mentioned, as well as their drawbacks and how the maglev system attempts to remedy those problems.

The term “Levitation” refers to a class of technologies that uses magnetic levitation to propel vehicles with magnets rather than with wheels, axles and bearings. Maglev (derived from magnetic levitation) uses magnetic levitation to propel vehicles. With maglev, a vehicle is levitated a short distance away from a “guide way” using magnets to create both lift and thrust. High-speed maglev trains promise dramatic improvements for human travel widespread adoption occurs. Maglev trains move more smoothly and somewhat more quietly than wheeled mass transit systems. Their nonreliance on friction means that acceleration and deceleration can surpass that of wheeled transports, and they are unaffected by weather. The power needed for levitation is typically not a large percentage of the overall energy consumption. Most of the power is used to overcome air resistance (drag). Although conventional wheeled transportation can go very fast, maglev allows routine use of higher top speeds than conv.

Magnetism is a phenomenon that attracts people of all ages. Surprisingly, we know less about peoples' conceptions of magnetism than we do about other physical phenomena. We report the conceptions of magnetism of a number of groups.

The electromagnetic levitation system (MLS) is a mechatronic system already acknowledged and accepted by the field experts. Due to a synergic integration of the sensorial elements, the control subsystem and the actuating subsystem, the mentioned levitation system becomes an especially recommended subject in the academic curricula for mechatronic study programmes. This paper intends to initiate the investigation of different modelling, simulation and control possibilities for a magnetic levitation system starting from a real, physical reference model.
